Some special promotion mounts like Tyraels charger from the AP went AWOL with the patch. Mine is gone too. There is a bluepost on this that they are working on it. Seems they did

"It’s not the job of the artist to give the audience what the audience wants. If the audience knew what they needed, then they wouldn’t be the audience. They would be the artists. It is the job of artists to give the audience what they need."

I got really scared because it popped up in my mail on a level 1 character I used to check out another server... I didn't want to have to level it to 20
But I relogged to find it in my mount collection tab thing, so all gooood

I have the exact opposite problem. I just unfroze my account after a long break and made a new character. Tyrael's Charger has been sent to me 20 times. Anyone else experienced this? I am assuming they will just get deleted from my account eventually and everything will return to normal. As of right now my mailbox is filling up.
